If each "match" will belong to only one "tournament" while each "tournament" may relate to more than one "match" then create a "tournatmentID" in the "match" table. If you leave that NULL or, say, 0, then that match will not be in any tournament, else will be in the tournament with that tournamentID. On the other hand, if each match may relate to zero or more tournaments, and each tournament may relate to zero or more matches, then create a separate tournamentMembershipTable. > > Thanks, > Ian > _______________________________________________ > sqlite-users mailing list > [email protected] > http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users _______________________________________________ sqlite-users mailing list [email protected] http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
